Yet on a routine inspection of the U.S.S. Enterprise, Kirk's Starfleet career enters a new chapter as a result of his most vengeful nemesis: Khan Noonien Singh, the genetically enhanced conqueror from late 20th-century Earth. Escaping his forgotten prison, Khan sets his sights on both capturing Project Genesis, a device of god-like power, and the utter destruction of Kirk.
